摘要：
EFIT(Equilibrium Fitting) code is successfully transplanted for HL-2A tokamak pa-rameters.The evolution of the equilibrium configurations for shot 2898 is simulated.It is shownthat the discharge starts with a limiter configuration and develops into a divertor configurationgradually after t=200 ms.The latter lasts until the end of the discharge at t=900 ms.Theevolution of the major plasma shape parameters such as the boundary magnetic fluxes,the posi-tions of the x-point and magnetic axis,and the minor radii obtained are calculated and comparedwith the experimental results.The agreement between the simulation and experiments are shownto be reasonable.The possibility for discharge quality improvement is discussed.
